.30 Carbine ballistic test
Not too long ago the good people at MKS Supply sent me a new Inland M1 Carbine to review, you can read that review here. In researching the rifle and cartridge I learned that is was not considered the man stopper as the larger caliber rifles but as a carbine it sure was handy.
As with other calibers such as the 9mm Luger, ammunition technology has come a long way since the cartridge’s inception. So, I thought while I had the rifle handy, test ammunition left over, and freshly melted ballistic gel why not see what a difference the newer defensive type ammunition makes. I used all the same rounds from the accuracy test including original Lake City Match .30 Carbine.
First a little history on the cartridge.
U.S. Army specified for a new cartridge to be greater than .27, with an effective range of at least 300 yards. Based on the Army’s specifications Edwin Pugsley of Winchester begin with a .30 caliber, 100–120 grain bullet at a velocity of 2,000 feet per second. Initially cartridges were made by turning down rims on .32SL cases and loaded with .30 caliber bullets. The first 100,000 cartridges were headstamped “.30 SL”.
The .30 Carbine (or 7.62×33) was introduced in the 1940s and was designed for the M1 Carbine and an eighteen inch barrel. The .30 Carbine was developed by Winchester and is similar to the .32 Winchester Self-Loading cartridge in .30 caliber. Though they developed the cartridge they did not immeditally submit a carbine for testing.
The M1 Carbine appeals to re-enactments as well as sporting and collecting, not to mention recreational use. As a sporting cartridge it is good for small and medium-game and at best marginal for deer-size game. In carbines full metal jacket bullets do not expand must if at all but with the introduction to jacketed soft point and Critical Defense the .30 Carbine has gained a bit of an edge. Standard .30 carbine full metal jacket bullet weighs in at 110 grains. The .30 Carbine generates about half the muzzle energy of the typical .30-30 Winchester so it is not an ideal cartridge for many sporting purposes on larger animals.
Though all the full metal jacket penetrated through 3 layers and 32 inches of ballistic gel, I had two round that did well for expansion and not going through both blocks of gel, The Hornady Critical Defense and Federal jacketed soft point.
So, yet another round has benefited from advanced bullet technology to make it a more viable defensive round.
For those keeping score, that is another twenty some rounds through the Inland M1 Carbine without trouble, I realize an additional twenty rounds is not that much more to report but I am including all the information from the ballistic test in this article, including round count.
